Cubs will proceed cautiously with Cashner

CHICAGO -- Andrew Cashner, activated from the disabled list on Monday, will likely need two days off between outings as he continues to strengthen his right shoulder.

Cashner has not pitched for the Cubs since his only start on April 5. He was placed on the DL with a strained right rotator cuff after that.

How will the right-hander be used now?

"Carefully," Cubs manager Mike Quade said on Tuesday.

During his five Minor League rehab outings, Cashner would pitch one day, then take two off.

"I'll be more careful in how we use him," Quade said.

Cashner will get a chance to start in October, when he pitches for the Mesa Solar Sox in the Arizona Fall League. He will be joined in the AFL by Cubs prospects Josh Vitters, DJ LeMahieu, Chris Carpenter, Junior Lake, Trey McNutt and Marcus Hatley.

Grabow visits Children's Memorial Hospital

CHICAGO -- Cubs pitcher John Grabow took time out on Tuesday to do some coloring at Children's Memorial Hospital.

Grabow spent part of the afternoon with some of the patients at the hospital, passing out Cubs hats, talking baseball and helping them with their coloring.

"It's sad," Grabow said. "You see kids not feeling well, and it puts it in perspective when you have kids. ... It gets to you pretty bad.

"Every kid I saw today was in good spirits, even though they have a tough road ahead of them. It makes my job look a lot easier. These kids have so much anxiety about getting healthy. I get anxiety if the phone [in the bullpen] is going to ring to go face a hitter."

One of the patients he met was Mackenzie Tannhauser, 17, of Chicago, daughter of Ward Tannhauser, known as the "Ivy Man" because he has been spotted at Wrigley Field draped in faux ivy and standing on stilts. Mackenzie is waiting for a heart transplant and is writing about her progress on a blog. Grabow made sure to give her his email so she can update him on when she gets a new heart.

The kids seem to handle their situations well.

"It's the easiest thing for me to go down and try to put a smile on kids faces," Grabow said.

Extra bases

• Cubs infielder Blake DeWitt ran the bases and did some agility drills on Tuesday to test a tender left hamstring, but was still limited to pinch-hitting.

DeWitt has homered in three of his last six starts, including a three-run shot off the Giants' Tim Lincecum on Aug. 29. He was batting .261 for the season heading into Tuesday.

• The Cubs wanted to add another catcher when rosters expanded, but Welington Castillo was unavailable because of a hamstring injury that has sidelined him three times this season at Triple-A Iowa. Castillo was at Wrigley Field on Tuesday to be examined by the Cubs' medical staff. He was not expected to be ready before the regular season ends.

• The Cubs' players and front office staff posed for the team picture on Tuesday. It was missing a general manager -- Jim Hendry was dismissed last month -- and there could be a lot of new faces in 2012. Quade said he didn't think about that.

"Just put a smile on, and get it done," Quade said. "Just another picture day. There've been 30 some for me now."
